Roots blower test run for the new installation overhaul or blower must be unused for a long time commissioning. Concrete steps are as follows 1, under no-load condition jog power switch Check the motor rotation direction. Indicating the direction of rotation required cooling shroud fan cooling water valve should be open. 2, starts 30 minutes after the air operation to check for abnormal vibration and heat generation should be shut down if unusual circumstances pinpoint the cause. 3, no-load operation, no abnormal situation gradually close the vent valve reaches the rated pressure to observe the fan temperature and vibration current, voltage is normal. 4, the operation of the process on a regular basis to check the oil temperature, ammeter, bearing temperature is generally 15 minutes to check again. 5, shutdown must first relief, load shedding and then finally closed cooling water park. Roots blower from the chassis, panels, impeller, import and export muffler four major components. Wall: mainly used to connect the fan casing and impeller long Shaluo Ci, and supporting the impeller rotation, as well as play a seal effect. Impeller: the rotating part of the Xinjiang Roots blower fan, and two-leaf clover, but smaller than the outlet clover leaves two pulsating, Tianjin blower noise, smooth operation, many advantages Roots blower, has been gradually replaced by two leaf blower. Muffler: by reducing blower inlet and the noise generated due to flow fluctuation. High pressure blower has been widely applied in the field of wastewater treatment, mining, electric power, metallurgy, light industry, building materials, chemicals, flour, aquaculture, it is precisely because of the following makes excellent high pressure blower so popular. 1, using high-precision hardened synchronous transmission gears, bearings, long life equipment, low noise. 2, high pressure blower is compact, light weight, small size. 3, high precision rotor balancing, balancing rigorous testing, high-speed operation force balance, low vibration.
